Photos: 20 most important tech inventions of the past 100 years

​A century moves fast

Picture life in 1918: World War I was in its closing months, a Ford Model T cost $500, and home radio units were just coming into being. Now just 100 years later we live in a digital age. Unbelievably powerful and always-connected computers live in our pockets, self-driving cars are fast becoming reality, and listening to music is as simple as asking Alexa to play a favorite artist.

The technology we enjoy today would be largely impossible if not for these 20 inventions. While the inventions may seem simple by today's standards, our world was shaped by these marvels of the past century.
